The Hindu Business Line : ONGC reports 3 oil, gas finds on west coast, KG Basin

ONGC has reported three oil and gas finds — one in shallow-waters on the West Coast and two in the deep-waters in Krishna Godavari (KG) basin on the East Coast.

ONGC is the 100 per cent operator of this block since it was with it prior to the New Exploration and Licencing Policy (NELP) regime.

Giving out technical details, an ONGC statement said that in the western offshore region, the company had made a significant oil and gas find at a location 60 km south-south west of the Mumbai High Field. The well was spudded on October 20, 2004 in water depth of 82 m and completed to a depth of 3,949 m. Multiple oil and gas bearing sands have been identified in the Panna Formation and testing of the two objects had concluded. The deeper object has flowed 4,90,376 cubic m of gas per day and 2,491 bbl of oil per day through ½" choke. The shallower object has flowed 4,51,838 cubic m of gas per day and 2,045 bbl of oil per day through ½" choke.

The oil and gas are of high quality, the company said, adding that this find had opened up a new exploration opportunity in sands within the Panna Formation off Mumbai High field.

The integrated interpretation of 3D seismic data and analysis of attributes indicate a possible aerial extent of about 25 sq km, which is likely to increase after delineation drilling.

On the East Coast, ONGC made two more gas strikes in its on-going `Sagar Samriddhi' Deepwater Exploration campaign. Well VA-2 in block KG-OS-DW-IV at allocation 35 km off Amalapuram coast was spudded on March 24, 2005 in 689 m water depth targeting potential meandering channels.

The well has been completed to the target depth of 2,614 m encountering a total pay thickness of 17 m. On successful completion, the well flowed 3,26,545 cubic m of gas per day through 24/64" choke.

This prospect will be integrated to up-scaled exploitation plan of G-1 and GS-15 structures where ONGC is developing India's first digital oil field in the KG basin.

In another location in KG offshore, ONGC's drillship, Sagar Vijay, emerged third time lucky in its exploration campaign. This is again a strike in pre-NELP nomination block IG, where ONGC is the sole operator. Well G4-4, under drilling at a water depth of 331 m, is located 38 km from Amalapuram coast.

The well, targeted to explore the channel level complex in the area, has already established the presence of shallower pays hitherto not encountered in any of the drilled wells of G4 prospect.

Presence of gas has been confirmed while drilling and through wire-line testing. The lead through this strike would yield fresh impetus in the integrated development plan of G4 and GS-29 prospects, the company said.
